Rude telemarketer, claiming to call on behalf of Edgars.

Telemarketers are rude. I received a call from them this morning ***), with the caller indicating that they are calling from Blue Label Connect on behalf of Edgars. I was offered some airtime deal, which I declined. This afternoon I was called again from the same number. After the introduction, I mentioned that I had already received a call from them earlier today, upon which the caller promptly hung up without as much as a further word. One would expect a courteous end to the call, given that the recipient bothered to take the call in the first place. I have now blocked their number.
